There are basically 4 places for a diff to leak: the differential cover
gasket (which is what you are talking about), the pinion seal, and the
left/right output shaft seals.
There is a fifth place. If you overfill the diff by not all that much, it
will leak out the vent on the top. Voice of experience speaking. (How do
you overfill the diff? Have the rear end cage out and fill the diff through
the speed transducer hole to a level that “seemed to be about level with the
filler plug”:-))
